Abstract

The invention discloses a geopolymer-based corrugated tile. For overcoming various defects existing in currently used corrugated tiles, the geopolymer-based corrugated tile disclosed by the invention is prepared from 15-25% of liquid water glass, 25-33% of aluminosilicate, 2-6% of anti-bending reinforcer, 0.1-0.5% of anti-crack fibers, 43-50% of packing, 0.2-0.7% of dispersible emulsion powder, 2-3% of water, and 0.1-0.5% of water repellent. According to the invention, by taking geopolymer as a main raw material and adding the dispersible emulsion powder, the anti-crack fibers and the anti-bending reinforcer, the brittleness of the geopolymer-based corrugated tile is improved, and the flexibility and bending strength of the geopolymer-based corrugated tile are increased, so that the transverse bending strength reaches over 4500 N/m, and the vertical bending strength reaches over 350 N/m. The geopolymer-based corrugated tile disclosed by the invention is prepared by taking industrial waste residues as main raw materials, therefore, the raw material source is extremely rich; production and maintenance processes are performed under natural conditions and not at a high temperature, therefore, the corrugated tile is green and environment-friendly; and the maintenance time is short, the production cycle and the production space are greatly shortened, and the production cost is reduced.

Description

A kind of geopolymer base pantile

Technical field

Disclosed by the invention is a kind of geopolymer base pantile, belongs to material of construction preparing technical field.

Background technology

Pantile is the architectural roof cladding generally using, and as factory building, bicycle shed etc. are all often used pantile.At present domestic conventional roofing tile has cement asbestos tile, asbestos tile, polyvinyl chloride watt, polypropylene watt, Glass Steel Tile, color steel watt, cement tile etc.Because asbestos contain carcinogenic substance, so cement asbestos tile and asbestos tile are limited or ban use of; Polyvinyl chloride, polypropylene-base pantile are by recycling waste polyvinyl chloride waste and old polypropylene as raw material production, and environmental protection still needs high-temperature molding in producing pantile process, consumes the energy, and has improved production cost.Glass Steel Tile is easily aging.Color steel watt has easy processing, and the advantage of easily installing, is widely used, but the shortcomings such as that it also exists is not heat insulation, not sound insulation, oxidizable corrosion, and material cost is high, and steel-making energy consumption is large, big for environment pollution.Cement tile, comprises Portland cement watt, magnesia cement watt and the disclosed dolomite magnesia cement pantile of China Patent No. 201010541818.6, and its raw-material production all will be through calcining, and production process can cause more serious pollution to environment; Production cost is higher, and manufacture of cement pantile curing time is that more than 28 days the production cycle is longer, takies production site larger.Therefore, providing a kind of high-temperature molding that do not need, have the pantile of heat insulation, sound insulation, anticorrosive feature, is the needs of industry development, is also the effective measure that solve the existing deficiency of current pantile.

Summary of the invention

It is high that technical problem to be solved by this invention is to provide a kind of intensity, curing time is short, sound-insulating and heat-insulating effect is better, the ground polymers base pantile that production cost is low, overcome that existing pantile production energy consumption is large, production cost is high, not sound insulation, not heat insulation problem, can also improve the utilization ratio of national trade waste.

The present invention is achieved by the following technical solutions, and a kind of geopolymer base pantile is mainly prepared by the raw material of following quality percentage composition (wt%): liquid glass 15-25%; Silico-aluminate 25-33%; Anti-folding toughener 2-6%; Anti-crack fiber 0.1-0.5%; Filler 43-50%; Dispersible type latex powder 0.2-0.7%; Water 2-3%; Hydrophober 0.1-0.5%.Its preparation method is as follows:

(1) proportionally take various raw materials;

(2) first various dry powder raw materials are joined in stirrer and stirred regardless of order;

(3) in the dry mash fully mixing, add liquid glass and pro rata water, more fully mix form slurry;

(4) above fully mixed slurry is poured in pantile mould (specification 1800*720*4mm) and spread two-layer glass fiber net, strike off fixed-type.

(5) the maintenance demoulding in 6 hours under natural condition, then puts maintenance under field conditions (factors) 7 days.

(6) after in maintenance, colorant face is sprayed in the pantile front after 7 days, natural curing parches obtaining tile of finished product to pigment.

Described dry powder water glass is that industrial liquid glass modulus is 1.5-2.5, solid content 36%-45%;

Described silico-aluminate refers to 100-600 object blast furnace granulated slag, 100-600 object bessemer furnace slag, the mixture that any one or a few in 100-400 object flyash forms with arbitrary proportion;

The described type latex powder that dispersibles is commercially available vinyl acetic monomer and ethylene copolymer rubber powder or acrylate and styrene copolymerized rubber powder;

The mixture of a kind of or two kinds of arbitrary proportions that described anti-crack fiber is commercially available length in the polypropylene fibre of 5-7mm, trevira;

Described filler is the washed-out sand of 40-120 object or bright sand;

Described hydrophober is silicone based hydrophober;

Described anti-folding toughener is the mixture that PEO or CMC and PEG form by the weight ratio of 1:1.4.

Described service water glass, blast furnace granulated slag, bessemer furnace slag, flyash, anti-crack fiber, PEO, CMC, PEG, hydrophober, dispersibility latex powder are all commercial goods.

Take the present invention of above-mentioned measure, take geopolymer as main raw material, polymer dispersion powder, anti-crack fiber and anti-folding toughener in starting material, have been added, improved the fragility of geology polymers base pantile, snappiness and the bend resistance intensity of ground polymers base pantile have been improved, make more than horizontal folding strength reaches 4500N/m, longitudinal anti-folding is more than 350N/m.Add hydrophober, reduced the water-intake rate of pantile, average water-intake rate is less than 15%.Geopolymer is a kind of under the effect of alkaline matter catalyst, and a kind of inorganic polymer material that series reaction forms occurs.Ground polymers has that intensity is high, the feature fast, ageing-resistant, acid-alkali-corrosive-resisting of hardening, and the rational proportion of raw material of the present invention makes more than former anti-folding brings up to 1.0MPa.In addition the present invention adopts industrial residue as main raw material, originates very abundant, and production maintenance processes is all to carry out under field conditions (factors), does not need high temperature, environmental protection; Curing time is short, greatly shortens production cycle and industrial land, reduces production costs.
